Abstract

This chapter deals with a mathematical problem related to the equilibrium analysis of a membrane with rigid and cable boundary. The membrane and its boundary are respectively identified with a regular surface and a set of regular curves. The equilibrium is directly expressed by means of an elliptic problem, in terms of the shape of the membrane and its stress tensor; therefore, a free boundary numerical resolution procedure is presented and applied in a particular case.

If \(f(x,y)\) is a function, we will write \(f_{,x}=\dfrac{\partial f}{\partial x},\;f_{,y}=\dfrac{\partial f}{\partial y},\,f_{,xx}=\dfrac{\partial^2 f}{\partial x^2}\,\;\text{and so on}.\)
